Isaiah 33:21

But there the glorious Lord will be unto us a place of broad rivers and streams, that is, by virtue of the indwelling of God in the midst of His people the Church would be like a great city, which is both defended and watered by rich streams, wherein shall go no galley with oars, neither shall gallant ship, one of the mighty sail-ships which ventured out on the mighty ocean, pass thereby, Jehovah Himself being the defense of His people and protecting them against all enemies.
